* generic/tclCmdMZ.c: Correct [string is (wide)integer] failure
* tests/string.test: to report correct failindex values for
non-decimal integer strings. [Bug 1805887].
* compat/strtoll.c (removed): The routines strtoll() and strtoull()
* compat/strtoull.c (removed): are no longer called by the Tcl source
* generic/tcl.h: code. (Their functionality has been replaced
* unix/Makefile.in: by TclParseNumber().) Remove outdated comments
* unix/configure.in: and mountains of configury autogoo that
* unix/tclUnixPort.h: allegedly support the mythical systems where
* win/Makefile.in: these routines might not have been available.
* win/makefile.bc:
* win/makefile.vc:
* win/tclWinPort.h:
* unix/configure: autoconf-2.59
